TROLLEY-WIRE SUPPORT.

Specification of Letters Patent.

`Patented Mar. 1, 1921.

Application filed August 26, 1919. Serial No. 320,003.

To all whom t may concern:

Be it known that I, JOSEPH F. MONTINE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in TrolleyfWire Supports, of which the following is a specification.

This invention relates to supports for trolley wires employed in connection with apparatus for collecting and delivering mail matter, parcels, merchandise, etc., such apparatus consisting of a truck or carriage which is mounted for travel on an elevated cable track, and is driven by an electric motor obtaining current from an overhead trolley wire. Y

The invention has for its object to provide a novel and improved insulated support for the trolley wire, and to this end it consists in a combination and arrangement of parts to be hereinafter described and claimed.

In order that the invention may be better understood, reference is had to the accompanying drawing forming la part of this specification.

In the drawing, ,l

Figure 1 is a plan view of the support, and Fig. 2 is a central vertical section thereof. e

Referring specifically to the drawing, 5 denotes apole or post which supportstwo horizontally projecting bracket arms 6 carrying at their outer ends a plate 7 which serves as the supporting base of a standard 8 having at its upper end means for supporting the trolley wire 9. It will be understood that the trolley wire is supported in this manner at suitable intervals. The plate 7 also carries a supportvlO for a cable 11 forming an elevated track on which is adapted to travel a truckor carriage (not shown) which is driven by an electric motor obtaining current from the wire 9.

rIhe holder for the wire 9 consists of a bar 12 which is channeled to seat the wire, with the edges'of the channel clenched over to leave a smooth surface for the trolley wheel or other current collector. This holder has an aperture to receive the upper end of the standard 8, the latter being shouldered and riveted over the holder as shown in Fig. 2, whereby it is securely fastened to the standard'. e

In the plate 7 is an opening in which seats a tube 13 which is shouldered, as shown at 13a, to prevent it from slipping `through the opening.- The standard 8 passes through this tube and projects therefrom at both ends. v

The top of the tube 13 is closed by a disk 14 of insulating material having a central bottom portion extending slightly into the tube. .Over this disk is placed a hood 15 the side of which surrounds the upper portion of the tube and serves to protect the insulation disk 14. The standard 8 passes through the disk and the hood, and above the latter 1t carries a nut 16, the standard being threaded to -receive the same. The nut screws down against the outside of the hood to clamp the same down on the disk, and at the same time clamp the latter down on the upper end of the tube.

Below the plate 7 is another hood 17 into which the lower end of the Standardl extends. The top of this hood fits up against the under side of the plate 7, and it is clamped thereagainst by a nut 18 inside the hood and screwed on the standard, with nut and the hood. l

The tube 13 drops slightly below' the plate 7 vand it is stepped in an aperture 21 1n the top of the hood 17.

Upon tightening upthe nuts 16 and 18, the standard 8 is held securely in upright position, and it is effectively insulated from its supporting means by the diskV 14 and the Washer 20, both of said parts being of insulating material. The structure is very simple and eilicient and the parts can be readily assembled.

I claim: y Y

A trolley wire support comprising a standard having means for supporting the wire, an apertured base plate, a tube seating in the aperture of the base plate and projectingfrom the bottom thereof, through which tube the standard passes, a member of insulating material seating on thev top of the tube, a hood seating on said insulating member, and surrounding the same, a

' nut carried by the standard and engageable with the hood for clamping the insulating member to the top of the tube,V a hood tting against the under side of the base plateand having a topvrecess to seat the lower end of the tube, into whichl hoodthe lower end of the standard extends, a member of insulating material in the hood, and a nut on the standard for clamping said insulating member against the under sideo the last- 10 mentioned hood. 'n

In testimony whereof I aix my signature.

Jos-EPH F. MONTINE.
